UNITED STATES EARL J. WAGNER, 0F TAMAQUA, PENNSYLVANIA.

COAL JIGGER.

Application filed June 7,

T 0 all whom it may concern:

Be it known that I EARL J WVAGNER, residing at Tamaqua, l ennsylvania, acitizen of the United States, have invented. certain new and usefulImprovements in Coal Jiggers, of which the following is a specification.

My invention relates to jiggers for separating coal and slate andrelates to the kind in which a gyratory motion is imparted to the panwhich is suspended in the water holding tank and in particular myinvention aims to produce a simpler and therefore less expensively madeconstruction for producing the motion of the pan which is characteristicof the jigger of J. F. Wa ner Patent No; 1,288,311 issued December 1?,1918 and to enable adjustment of the extent of motion of the pan at thereceiving end according to whether the material is quick or sluggish inits motion which cannot well or advantageously be done in the case ofthe jigger of said patent. My invention consists in whatever isdescribed by or is'included within the terms or scope of the appendedclaims.

In the annexed drawings:

Fig. 1 is a side elevation with parts in section of a jigger embodyingmy invention;

Fig. 2 is a top plan view thereof.

By the mechanism of the jigger of the patent above mentioned thegyratory movement of the pan is produced by two sets of eccentrics whichrespectively impart a circular motion to the connection with the pan andan up and down motion only to the other connectionwith the pan, this upand down motion being produced by a lever which rocks on a fixed pivotso that the eccentric means is formed to impart no movement except therocking movement to such lever. Such a construction is more expensive tomake than is desirable for commercial requirements and does notcommercially lend itself to adjustability of theamount of'motion of thepan which is desirable to suit the nature of the coal and slate beingjigged so that it is necessary to suit each jigger gyrating mechanism tothe requirements of the particular material being handled.

Describing in detail the embodiment of my invention shown in thedrawing, the supporting framework, 10, the water tank, 11, and the pan,12, with the automatic slate discharge, 13, are of usual constructionand are similar to what is shown in the before 1923. Serial m3. 643,966.

' rotate the shaft, to which shaft are keyed two eccentrics, 16, ofordinary construction, which are connected by suspending plates, 17 ,'tothe opposite sides of thepan by bolts,

18, at or near the discharge end of the pan, 1

the pan being thus suspendedfrom the two eccentrics and acircular'motion being imparted to the discharge end of the pan by sucheccentrics.

J ournaled in bearings, 19,upon the framework, 10, above the receivingend of the pan, 12, is a rock shaft 20, which iscon nected with theopposite sides of the pan by crank arms, 21, pinned or keyed to theshaft and links, 22, that at their upper ends are pivoted by a pinor'bolt, 23, to therespective crank arms, and at their lower ends bypivots, 24, are pivoted to the respective sides of the pan. A rocking,motion is imparted to the shaft,'20, in unison, with the rotation of theshaft, 15, by an eccentric, 25, keyed to the shaft, 15, the strap, 26,of

which is of ordinary construction and connected by a simple push andpull bar or link, 27, 'with a crank arm, 28, pinned or keyed to the rockshaft, 20. It will be seen that the rock shaft, 20, and the crank arms,21 and 28, are in effect a bell crank lever, one arm (the crank 21)extending in a horizontal direction and the other arm (the crank 28)extending vertically or crosswise of the bar or link, 27, so that byreason of the jointed connection between the link, 27, and the crank,28, there may be a horizontal to and fro movement of the link, 27, withthe eccentric, 25, as well as an up and down movement and hence theeccentric and strap construction, 25 and 26 may be thecustomary-construction and yet the gyratory motion which it is desiredtoimpart to the pan throughout its extent and the mainte nance of thepan in a horizontal orsubstantially horizontal position are secured.

But a single eccentric, 25, and its-connections with the rock shaft, 20,is required and the same may be located either at one side of the panand framework, 10, or as shown in the drawing it may be placed in theplane at the transverse center of the centric pitman, 27, and the crank,28, .ad-r
